Abstract

The invention discloses a refining method of sea buckthorn oil. The method adopts the supercritical CO2 fluid extraction technology to purify sea buckthorn fruit oil from a sea buckthorn fruit original extract. During extraction, the sea buckthorn fruit original extract is poured into a material barrel of an extraction kettle, CO2 gas is injected into the extraction kettle, the temperature and pressure in the extraction kettle are kept at a supercritical state of CO2 gas, the CO2 gas contacts the sea buckthorn fruit original extract to make sea buckthorn fruit oil dissolve in supercritical CO2 fluid, and then the supercritical CO2 fluid containing sea buckthorn oil enters a separation kettle to conduct decompression resolving, and then the effective components are collected. The method provided by the invention adopts supercritical CO2 fluid as the extraction solvent, the solvent is recycled in the same system, the solvent has small consumption, is non-toxic and cheap, therefore the extraction cost is low. Also, the extraction temperature of the method is low, thermosensitive substances in the product are not easy to damage, and the energy consumption is low. The extracted sea buckthorn fruit oil has the characteristics of high purity, no peculiar smell, and no solvent residual, etc.

Background technology
Sea-buckthorn, also known as doing vinegar willow, is Elaeangnaceae hippophae plant, is the 190 various active materials such as a kind of defoliation small arbor, rich vitamin, trace element, amino acid and flavones.In China, sea-buckthorn is mainly distributed in northern and west and south region-by-region, resource relative abundance.Oleum Hippophae mainly extracts and comes from sea buckthorn fruit, and containing Zoomeric acid, stearic acid, linolenic acid, linolic acid, vitamin-E, carotene etc., have reducing blood-fat, antiulcer agent, effect such as raising immunizing power, beauty treatment etc.Given this, the wide market of Oleum Hippophae, has attracted concern and the research of a large amount of scholar.At present, the method for conventional extraction Oleum Hippophae is milling process and solvent extraction method, and the former oil yield is low, and easily destroys heat-sensitive substance; The latter uses a large amount of organic solvents, and product has dissolvent residual, has peculiar smell, and purity is low, and energy consumption is high.
Summary of the invention
The object of the present invention is to provide a kind of process for purification of Oleum Hippophae, the method technique is simple, consuming time short, can improve again DNA purity and the extraction yield of Oleum Hippophae, not destroy heat-sensitive substance, reduces environmental pollution, reduces extraction cost.
Technical scheme of the present invention: a kind of process for purification of Oleum Hippophae, comprises the following steps:
(1) choose after henna Fructus Hippophae is smashed to pieces and squeeze the juice, and centrifuging, extract sea buckthorn juice;
(2) put Medium speed filter paper in the two-layer screen cloth bottom the material barrel of extraction kettle, then sea buckthorn juice is poured in the material barrel of extraction kettle, by CO 2gas inject extraction kettle, in maintenance extraction kettle, temperature and pressure is at CO 2the supercritical state of gas also makes it to contact with sea buckthorn juice, makes Oleum Hippophae be dissolved in supercritical CO 2among fluid;
(3) make the supercutical fluid containing Oleum Hippophae enter separating still decompression from extraction kettle through throttling expansion and parse Oleum Hippophae, and collect.
In aforesaid method, described supercritical state temperature is 45 ~ 60 DEG C, and pressure is 15 ~ 25MPa; CO 2gas is 150 ~ 200kg/h by the flow of extraction kettle, and extraction time is 3.5 ~ 5.5h.
In aforesaid method, the condition that described decompression is resolved is separating pressure 5.5 ~ 6.0MPa, and separation temperature is 50 DEG C.
In aforesaid method, described collection puts into homogenizer by from the Oleum Hippophae with a collection of raw material abstraction, homogeneous rear filling, and lucifuge stored refrigerated.
Owing to adopting technique scheme, the invention has the advantages that: compare with low-pressure supercritical extraction method with existing milling process, the present invention not only Extracting temperature is low, energy consumption is little, be not easy to destroy the heat-sensitive substance in Oleum Hippophae, energy consumption is low, and the Oleum Hippophae extracted has the advantages such as purity is high, free from extraneous odour, no solvent residue.In addition, the CO under the present invention's above-critical state 2fluid, as extraction solvent, recycles in same system, and not only technique is simple, and energy consumption is low, and solvent-oil ratio is little, and price is cheap, therefore extracts cost low.
